signors to Vizofiim Manufacturing Corporation, New York, N.Y., a corporation of New York Application August 5, 1953, Serial No. 753,243 2 Claims. (Cl. 5329) The present invention relates to a sales package and method of forming same, and particularly to sales packages for fresh leafy vegetables.

The primary object of the invention is to provide a bag and method of forming same which can be filled and closed on automatic bag filling and closing equipment while leaving an access opening to permit inspection of the vegetables therein.

Another object of the invention is to provide a bag and method of forming same which can be formed on conventional bag forming equipment.

A further object of the invention is to provide a method of forming a bag which includes severing the sides of the bag while simultaneously heat sealing the sides together.

Other objects and advantages will become apparent in the following specification when considered in the light of the attached drawings, in which:

Figure l is a front elevation of a bag formed in accordance with the invention.

Figure 2 is a vertical cross-section taken along the line 22 of Figure 1, looking in the direction of the arrows.

Figure 3 is a view similar to Figure 2 of the bag after filling and closing.

Figure 4 is a horizontal section taken along the line 4-4 of Figure 1, looking in the direction of the arrows.

Figure 5 is a semi-diagrammatic illustration of the bag forming, filling, and closing steps in utilizing the invention.

Referring now to the drawings in detail wherein like reference characters indicate like parts throughout the several figures, the reference numeral indicates generally a bag constructed in accordance with the invention.

The bag 10 includes an elongated rear panel 11, a somewhat shorter front panel 12 arranged in generally parallel relation to the rear panel 11 and integrally joined thereto at the bottom edge 13 of the bag 19. A transverse strip 14 is positioned between the rear panel'll and front panel 12 extending from its lower edge 15 spaced below the upper edge 16 of the front panel 12 to its upper edge 17 spaced below the upper edge 18 of ,the rear panel 11.

The rear panel 11 and the front panel 12 are joined together along their adjacent side edges 19, 20 and the adjacent edges of the strip 14 are secured therebetween intermediate the edges 15, 17 of the strip 14.

Referring now to Figure 3, the bag 10 is illustrated filled with a leafy vegetable 21 and with the strip 14 sealed to the rear panel 11 at 22 closing the bag to secure the leafy vegetable 21 therein. As can be seen in Fig ure 3, the strip 14 is not sealed to the front panel 12 and access to the leafy vegetable 21 can be gained between the upper edge 16 of the front panel 12 and the strip 14 to permit the hand to be inserted therebetween for inspection of the vegetables 21.

r 2,929,180 Fatented Mar. 22, 1960 The bag 10, as seen in Figures 1' and 2, has a machine loading lip 23 which is that integral portion of the rear A second roll 25 of substantially narrower width is posi-- tioned adjacent one end of the roll 24 to provide materialv from which the strip 14 is formed.

The material from the rolls 24, 25 is fed through a: folding station generally indicated at 26 to fold the front panel 12 along the lower edge 13 into overlapping relation with respect to the rear panel 11 and the strip 14.

Following the folding station 26 a severing station 27 is provided including a heated knife 28 to separate the bags 10 and simultaneously seal the rear panel 11, front panel 12 and strip 14 together along the side edges 19, 2th of the bag 10.

A conveyor 29 conveys the bags 10 to a filling station 30 wherein the leafy vegetables 21 are placed in the bags 19. The bags 11} are then fed to a closing station gen erally indicated at 31 which includes a heated knife 32 to simultaneously sever the loading lip'23 from the bag 10 and join the strip 14 to the rear panel 11 at 22.

The bags 10 are fed from the closing station 31 to a packing station 33 for packaging for shipment.

It should be understood that the loading lip 23 is used in the loading station 39 to assist in supporting the bag 19 during the placing of the leafy vegetables 21 therein. With the method illustrated in Figure 5, the bags 16 can be formed more cheaply with a materially reduced number of operations while permitting a nearly automatic production line to be established.

Having thus described the preferredembodiments of the invention, it should be understood that numerous structural modifications and adaptations may be resorted to without departing from the scope of the appended claims.

What is claimed is:

1. The method of forming and filling a bag which comprises feeding a relatively narrow strip in superposed relation to a simultaneously fed relatively wide strip, folding said wide strip along an edge parallel to said narrow strip with the folded portion of said wide strip terminating intermediate said narrow strip, simultaneously severing and sealing the side edges of said bag, filling said bag and severing a portion of said bag and simultaneously sealing together the edges formed by said last named severing step following the filling of said bag.

2. A method as claimed in claim 1 wherein the first combined severing, and sealing step heat seals the side edges of said bag securing the side edges of said bag together and simultaneously securing the side edges of said relatively narrow strip thereto;
